将DM9000编译进u-boot，在Makefile (u-boot-2016.05\drivers\net) 中添加
obj-$(CONFIG_DRIVER_DM9000) += dm9000x.o同时，在Smdk2440.h (u-boot-2016.05\include\configs)中定义CONFIG_DRIVER_DM9000，同时屏蔽掉CS8900相关信息。
/*
* Hardware drivers
*/
#define CONFIG_DRIVER_DM9000
//#define CONFIG_CS8900/* we have a CS8900 on-board */
//#define CONFIG_CS8900_BASE0x19000300
//#define CONFIG_CS8900_BUS16/* the Linux driver does accesses as shorts */
编译，出现BUG“DM9000_DATA ” is not define，仿照At91sam9260ek.h (u-boot-2016.05\include\configs)DM9000的相关配置，在Smdk2440.h (u-boot-2016.05\include\configs)配置
/*
* Hardware drivers
*/
#define CONFIG_DRIVER_DM9000
#define CONFIG_DM9000_BASE 0x20000000
#define DM9000_IOCONFIG_DM9000_BASE
#define DM9000_DATA(CONFIG_DM9000_BASE + 0x4)
